摘要：

Changji-Guquan UHVDC project is the first ±1100kV UHVDC project in the world, with transmission capacity 12GW and DC line length about 3320km. Design experience and theoretical study of this ±1100kV/12GW UHVDC project, still incomplete, need to be studied. In this article, based on the ±1100kV UHVDC project, main technical route and research ideas of the ±1100kV UHVDC project engineering practice are given. And the system design scheme, including main circuit topology, converter transformer short-circuit impedance selection, main circuit parameters, reactive power compensation and AC filter design, DC filter design, overvoltage and insulation coordination, indoor and outdoor DC yard selection, live maintenance for DC filter, conceptual design of valve hall, DC yard and main equipment and so on, are researched and discussed in depth. All of the research results above are adopted for the ±1100kV UHVDC project construction. The study results will provide theoretical and experimental experience for other ±1100kV and ±800kV UHVDC projects. © 2018, Power System Technology Press. All right reserved.
